Some data transfer methods will encrypt data one byte at a time or in groups of larger data blocks. In this video, you’ll learn how block ciphers combine data encryption with speed and efficiency.
Our modern applications make extensive use of cryptography. In this video, you’ll learn the basics of cryptography and some of the history of ciphers and secrecy.
Symmetric encryption often uses block ciphers or stream ciphers to create ciphertext. In this video, you’ll learn how block and stream ciphers work and what methods these ciphers employ to keep your information private.
The topic of cryptography is one of the most comprehensive in network security. In this video, you’ll learn about the history of cryptography and some of the early methods of encrypting and decrypting messages.
